SAW-FILING MACHINE.

5PBCIFICATION forming part of Letters Patent No. 367,561, dated August 2, 1887.

Application filed July 2, 1886. Serial No. 206,956. (No model.)

To aZZ whom it may concern:

Be it knownthat 1, JOHN HERMANSODEE,

of Seattle, in the county of King, Vashington;

Territory, have invented a new and Improved Saw-Filing Machine, of which thefollowing is a full, clear, and exact description. 1

My invention relates to the construction of a machine which may be used for the sharpening or filing of either circular-or gang saws, and which, by slight adjustment, may be employed as a saw-gumming machine.

The invention consists of an improved form; of file and file-holder and of an improved mechanism for cleaning off the burr produced in the sharpening of the saw, and of many other novel constructions and combinations that are fully illustrated in the drawings, and will be hereinafter described, and specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the figures.

Figurel is a plan view of myilnproved form of saw-filing machine, a portion of the machine being broken away to disclose a mechanism that would otherwise be concealed. Fig. 2 is a plan view of the saw-holding attachment, the two figures named together giving a complete plan view of the machine. Fig. 3 is a longitudinal sectional elevation taken on line at a: of Fig. 1. Fig. 4 is a side view of the machine in partial section on line y y of Fig. 1. Fig. 5 is a front view of the machine, the view being taken in partial section 011 line e z of Fig. 1. Fig.6 is an enlarged sectional detail view taken on line 1) v of Fig.5, the saw and the washer arranged in connection therewith being, however, shown in section. Fig. 7 is a sectional detail view taken on line '10 w of Fig. 6. Fig. 8 is a side view of the machine, the view being, however, taken uponthe side opposite to that illustrated in Fig. 4. Fig. 9 is a rear elevation of the machine. Fig. 10 is a plan view of the saw-holding attachment, representing the same as arranged for use in connection with a gang-saw. Fig. 11 is a dctail sectional view of the construction illustrated in Fig. 10. Fig. 12 is asectional view of the file-holder. Fig. 13 is a detail View upon a saw.

' The main body of the machine illustrated in the drawings above referred to is supported by a frame which consists of two upwardly spaced by an apron-like casting, 11, and are connected by tie-rods 12, which pass through the standards and lugs formed upon the apron, as is best shown in Fig. 9. In the upper ends of the standards 10 there are formed bearings in which the power-transmitting shaft 13 and a shaft, .14, supporting a frame to be presently described, are mounted, the bearings being completed and the standards being braced by an upper casting, 15, which is bolt-ed to the upper ends of the standards by bolts 16, arranged as clearly shown. The casting 15 is formed with two downwardly-extending arms, 17 and 18, in addition to the arms by means of which connection is made with standards, and these arms 17 and 1S carry journal boxes or bearings 19 and 20, the bearing 19 serving as the outer support for the main shaft 13, while the bearing 20 supports the inner end of said shaft and also supports the shaft 14.. The shaft 13 carries a loose pulley, 21, and a fast pulley, 22, the driving belt (through the medium of which power is transmitted to the machine) being shifted by any of the ordinary forms of belt-shifting attachments.

Near the inner end of the shaft 13 there is secured a conepulley, 23, which, through the medium of its belt 24, drives the file-carrying shaft 25, which shaft is mounted in bearings carried by a frame, 26, that is suspended by arms 27 from the shaft 11, the belt 24 running in engagement with a cone-pulley, 28, that is carried by the said shaft 25.

Upon the end of the shaft 25 there is sccu red a file -holdcr, 30, the construction of which is best shown in Fig. 12, Sheet 2, of the drawings. This holder consists of a main body, 31, that is secured to the shaft 25, and formed with two outwardly-extending wings, 32, that are provided with ribs 34, which are concentric to the axis of the holder. Olamping-pieces 33 are arranged in connection with each of the wings, and are formed with ridges 35, which extend beneath the ridges 3* of the wings 32. The plates 33 are secured to the wings 32 by means of bolts or set-screws 37. It will be noticed that the approaching faces of the wings 32 are not in the same perpendicular plane, and in practice the parts are so proportioned and formed that when the files 36 are placed in position so that they rest against the ribs 34 and are clamped in place by the plates 33 the inner side face of one of the files will be in about the same perpendicular plane as the outer side. face of the opposite file. By this construction both edges of the saw-tooth will be filed at the same time, for as the file-holder is removed the file-face Will operate upon the edge (I of the sawtooth (2, while the facef of the file will operate upon the edgeg of the said tooth, as clearly track or way, 38, upon which there rides a carriage, 39, a dovetail groove being formed in the under face of the block or carriage to engage with the way 33, as is best shown in Fig. 5. The carriage or block 39 carries a wheel, 40, provided with two pins, 41, said pins being arranged on opposite sides of the wheel or disk 40 and riding in grooves formed in the sliding bars 42, that are held to the carriage by a spring-clip, 43, which passes through a stirrup, 44, as best shown in Figs. 5 and 8. Upon the ends of the bars 42 there are mounted burr removing knives 45, the points ofsaid knives being arranged in opposition and the knives being secured to the bars by setserews 46, which pass through slots formed in the shanks of the knives.

being square and riding in' a bracket, 48, which extends inward from the side frame, 10. Upon this square portion of the shaft 47 there is mounted a crank-arm, 49, which, through the medium of a link, 50, is secured to a trippinglever, 51, that ispivotally connected to a bracket, 52, arranged as best shown in Fig. 5, said trippinglever 51 being arranged in the path of a lug or projection, 53, that is carried by a disk, 54, said disk in turn being carried at the lower end of an inclined shaft, 55, which is mounted in brackets 56 and 57, which project outward from the standard 10. Upon the upper end of the shaft 55 there is a gear, 58, which is engaged by a worm, 59, carried by the shaft 13, this construction being best shown in Figs. 1 and 5. A spring, '60, is connected to the link 50, and tends to throw the parts to the position in which they are shown in Fig. 5that is, to a position so that the jaws of the knives will be separated-but as the shaft is revolved through the medium of its connection with the main power-shaft of the machine, the lever 51 will be thrown in the direction of the arrow, thus partially rotating the shaft 47, and thereby causing the knives to be advanced until their edges overlap; but

will act to throw the parts back to the position shown in Figs. 5 and 9, this reverse throw being limited by a pin or stop, 61, that is carried by the lever 49, said pin abutting against the bracket 48.

Upon the under side of the disk 54 there is a cantface, 63, that is borne upon by a roller, 64, carried by the crank-arm of a rockshaft, 66, that is mounted in proper bearings at the rear of the machine. Upon the opposite end of the rock-shaft 66 there is secured a lever-arm, 67, formed with a central longitudinalslot, 68, which is normally held in the position shown in Fig. 4 by means of a spring, 69. This lever 67 is connected with the frame 26 through the medium of a connecting link or bar, 70, that is made in sections, one of which is formed with a longitudinal slot, 71, while the other is provided with a guiding screw, 72, and a guiding. or set screw, 73, connection between the lever and the connectingrod being established by means of a block, 74, and asetserew, 75, arranged as best shown in Figs. 1 and'4. The frame 26 and carriage 39 are connected by links 77.

On account of the connections described it will be seen that as the shaft 55 is revolved the cam-face 63 will act through the medium of its connection with the rock-shaft 66 to throw the frame 26 forward, the roller 64 being at all times held in close connection with the cam-face 63 through the action of the spring 69, and it will also be seen that as the frame carrying the files is advanced the carriage 39 will also be advanced, so that the relative position of the files and carriage will not be changed.

In connection with the machine just de scribed, I arrange a carriage, 80, which is formed with. a dovetail groove, 81, that rides upon ways 83, that are formed upon a longitudinally-slotted base-plate, 84, this bed being supported by end strips, 85. In the center of the carriage there is mounted a vertical shaft, 86, the lower end' o'fwhich is provided with a ratchet-wheel, 87, that is engaged by a spi'ingpawl, 88, carried by a lever, 89, said lever being pivotally connected to the lower end of the shaft 86. To the outer end of the lever 89 there is connected a link, 90, the extending end of which is adjustably connected to a lever, 91, that is mounted upon a block,

92, arranged as best shown in Fig. 1. The connection between the link 90 and the lever 91 is established through the medium of sockets 93 and 94, the connection between the socket 93 and the lever 91 being a swivel connection, while that between the two sockets is also a swivel connection, the connecting-rod being clamped within the socket 94 by a set-screw, 82.

Upon each end of the bed 84 there is secured a guidingsheave, 95, and upon the block 92 there is secured a drum, 96, that is provided with a cranlearm, 97, a chain or rope, 98, being wound about the drum and arranged to pass over the sheaves 95, the ends of the chain or rope 98 being secured to thecarriage 80.

From the construction described it willbe seen that by moving the lever 91 forwardin the direction of the arrow shown in Fig. 8 the shaft 86 will berevolved in the direction of the arrow shown in connection therewith, and it will also be seen that by turning the drum 96 through the medium of its crank-arm 97, the carriage will be drawn toward or from the main body of: the machine, the motion of the carriage depending upon the direction of rotation given to the drum.

The block 92 serves as the support for a rock-shaft, 100, to one end of which there is secured a lever, 101, the other end of the shaft passing in a groove, 102, beneath the carriage 39,and through the socket of an arm, 103, the inner end of the shaft 100 being square or irregularly formed, and the socket of the arm 103 being correspondingly formed, the arm being arranged between the inner face of the carriage and a loop, 101, that is secured thereto.

The upper end of the arm 103 is connected to an arm, 105, of a rock-shaft, 106, which rock-shaft is mounted in an upwardly-extending boss formed upon the carriage 39. A step, 107, is secured to the rock-shaft 106, and arranged so as to be thrown down to the position shown in Fig. 1 or to be raised to the position shown in Fig. 5. \Vhen thrown down, the stop 107 acts as a catch against which the teeth of a circular saw may be thrown in order that they may be in proper position to be operated upon by the segmental files described.

In operation the saw 110, as best seen in Fig. 6, is rigidly connected to the shaft 86 by means of a washer, 111, and a nut, 112. The earriage S0 is then advanced, so as to bring the teeth of the saw against the stop 107. \Vhen the saw has been moved to this position, the stop 107 is thrown up and the tiles are allowed to come into operation against the teeth of the saw, the frame 26 gradually advancing and carrying with it the carriage 39 until the tooth has been properly filed upon both edges, which filing upon both edges is rendered pos sible owing to the peculiar mounting of the files, the tooth entering the angle formed by the inclined faces of the files after the tooth is filed. The carriage 39 will commence to recede, and as it so recedes the edges of the knives 45 will be forced toward each other and will remove the burr formed by the action of the files.

\Vhen it is desired to file gang-saws, the knives 45 are removed and a frame, 120, (see Fig. 10,) formed with a rack, 113, is placed upon the carriage 80, the saw shown at being clamped to the frame 120. The rack 113 is engaged by a gear, 116, that is carried by the shalt 86, the frame being properly guided by a diagonally-arranged extension, 117.

From the construction described it will be seen that as the shaft 86 is rotated the frame 112 will be advanced, and this advance is made step by step as each tooth is filed.

Having thus fully described my invention,

what I claim as new, and desire to secure by Letters Patent, is
